Underdog Files First 7 Sports Contracts for Its Own Prediction Exchange

Underdog has filed the first seven sports event-contract templates for UDX, the federally regulated exchange it acquired in March. The filings target an initial listing no later than July 17, moving Underdog closer to controlling its own contracts rather than relying exclusively on outside exchanges.

Key Takeaways

• UDX self-certified seven sports contract templates with the CFTC on July 15.
• Filings target first contract listings no later than July 17.
• Underdog bought Aristotle’s exchange and clearing entities in March.

Underdog moves from distributor to exchange operator

Underdog’s newly acquired exchange self-certified seven sports event-contract templates with the Commodity Futures Trading Commission on July 15, according to the regulator’s product database. Aristotle Exchange DCM Inc., operating as UDX, said in the filings that it intended to list the first contracts for trading no later than July 17. The documents establish a launch target but do not themselves confirm that public trading has begun.

The certifications cover three baseball and three basketball templates resembling familiar game-winner, winning-margin, and total-score markets. A seventh, broader contract would allow markets on whether a named athlete, team, or other entity achieves an outcome during a defined period. The CFTC database lists all seven products as certified binary-event swaps.

The contracts have a $1 notional value and may trade between $0.001 and $0.999. UDX said trading would generally remain available outside announced maintenance windows and that at least one market maker would provide liquidity. Its baseball-total filing sets a 2.5 million-contract participant position limit and a 25 million-contract limit for market makers.

Underdog acquired Aristotle Exchange DCM and its affiliated derivatives clearing organization in March, saying the purchase would allow it to offer products through an exchange it owns. Before the acquisition and through its current customer setup, Underdog operated primarily as an intermediary offering access to contracts listed by other federally registered venues.

Underdog’s public documentation currently says some accounts route trades to Kalshi, while others remain powered by Crypto.com’s Derivatives North America, also known as Nadex. Running UDX would give Underdog greater control over contract design and settlement rules while reducing its dependence on third-party exchanges, although those existing relationships may continue alongside the new venue.

The entity-outcome template permits contracts involving athletes, teams, match winners, tournament advancement, championships, rankings, and statistical thresholds. The filing also allows multiple entities to be combined using AND logic (where every condition must occur) or OR logic (where one qualifying outcome is sufficient). That structure could support parlay-like products, although UDX does not use the term “parlay” or identify a specific combined contract it plans to list.

The filings are self-certifications rather than affirmative CFTC approvals: UDX certified that the products comply with the Commodity Exchange Act and commission regulations, while the regulator’s database records them as “Certified.” A separate UDX rule amendment supporting request-for-quote functionality remains under a 10-day review, indicating that some planned exchange features may follow the first product listings.

The move comes as the CFTC considers its first comprehensive framework for sports event contracts. The commission’s proposal would permit most conventional outcome markets while restricting products tied to injuries, officiating and certain discrete in-game actions. UDX’s first filings concentrate on game outcomes, scoring totals and broader competitive results — product categories that would generally remain permitted under that proposal.

The certifications move Underdog beyond merely displaying contracts supplied by other exchanges. Once UDX begins listing the products, the fantasy and sports gaming company will also control the regulated venue where at least part of its prediction-market inventory is created, traded, and settled.
